When should I test and/or how often should I test?

Updated 1 week ago by Michelle Pool

There are so many different opinions out there so we have decided to give you some information on what we do and also provide you with some excellent resources that we feel are based on science and testing. 

The best time to test is when it is convenient for you. Consistency is important when testing. How often to test really depends on what you are looking to achieve

These are some suggestions on when we test. 

1) FBG- Fasting blood glucose and ketones- after an hour of waking (before drinking and eating)- please be aware of the dawn effect, glucose will be higher in the morning and ketones are generally at their lowest.
2) Test at noon before a meal.
3) Test for glucose and ketones at before an evening meal. Testing twice a day will give you a picture of what fluctuations are occurring and an overall baseline of what is normal for you.
4) In addition to those times I do curiosity testing, That is before a meal and at 40, 80 and 120 mins after eating to see what reactions certain foods are causing.

Please note that glucose strips give better indications of food reactions, this is because glucose fluctuates faster than ketones. For example, glucose reaches its peak one hour after eating. Ketones take much longer to generate. 

Below is a list of people and websites. You will find differing opinions here.  If you start checking these folks out as well as search Facebook for groups to join with other ketogenic folks you will likely find the info you are looking for.
